When using Trap Exploder/SDC-TrapX I am seeing that the source address is set to 0.0.0.0 and Spectrum receives as an unknown trap. Why is this not working correctly?

Issue/Introduction

Why does Trap Exploder/SDC-Trapx send the source ip address to Spectrum as 0.0.0.0 for SNMPV2c traps?  How can I fix this so that the traps are not sent as unknown traps?

Environment

TrapExploder/SDC-Trapx

Resolution

If the device sends v2c traps without the snmpTrapAddress, enable the following option:

v2c_agentaddr_is_srcaddr

This option makes the v2c trap agent address the same as the source.

For SDC-TrapX (Trap Exploder is no longer supported) the corresponding option is:

agentaddr_is_srcaddr_translated_v1

This command works with translate_v2c_traps and translate_v3_traps, when translate_v2c_traps or translate_v3_traps are turned on, this makes the v2c trap or v3 trap agent address as the
source address. By default it is commented out.
